A toy rocket is launched straight up from the top of a building. The function that models the height as a function of time is

. At what height was the rocket launched?

1 answer

The height the rocket was launched at can be found by looking at the initial value of the function. The function represents the height as a function of time, so the initial height of the rocket is the value of the function at time t=0.

Therefore, to find the height the rocket was launched at, we need to evaluate the function at t=0. This would give us the initial height of the rocket.
